Advanced geotechnical engineering applications, such as shale gas extraction, CO2 geological sequestration, and geological radioactive waste storage, often involve various types of shales located at significant depths. Shales exhibit mechanical properties ...
Recent studies demonstrate novel metamaterials featuring unique properties by combining origami-inspired designs with additive manufacturing. In particular, the use of flexural hinges endow distinct advantages toward miniaturization and fabrication; howeve ...
The fault cores of extensional faults in Mesozoic limestones and dolostones are examined by mean of combined microstructural, ultrasonic and petrophysical analyses. Grain-supported fault rocks commonly localize in the outer fault cores, whereas matrix-supp ...
Shales have become increasingly important because they play key roles in modern energy and environmental geomechanics applications, such as nuclear waste storage, non-conventional oil and gas operations and CO2 geological storage. Shale behaves in a quasi- ...
Results of a strength-based optimisation of flexural hinge shapes are given. Both pre-defined and freeform parametric shapes are considered. By employing nonlinear parametric optimisation algorithms, shapes that are best suited for the desired applications ...
In central Europe, many geo-energy reservoirs have revealed to be hosted in transverse isotropic crystalline rock, where the rock's mechanical and hydraulic transport properties are poorly constrained. Here, we performed triaxial experiments on Cresciano G ...
